Electromagnetic Induction
... when you move the magnet more or less quickly, and when you put the north or south pole into the coil first. Then try other relative motions and positions, including some where the axes of the magnet and the coil are perpendicular. Does it make a difference if you move the coil, rather than the magn ...

... The LEVITRON is formed by a top that hangs above a base while is spinning. The 'antigravity' force that repels the top from the base is magnetism. Both the top and the heavy slab inside the base box are magnetized, but oppositely. Think of the base magnet with its north pole pointing up, and the top ...

Electrostatic charges in vx B 1 fields: the Faraday disk
... Lorrain (1990) gave an interesting discussion concerning conducting media that move in magnetic fields, focusing on steady-state conditions and disregarding terms of the order of v 2 /c2 . It seems, however, that some of his results are either wrong or derived in a wrong way for the following reason ...

... "A remarkable misconception on this point seems to be somewhat generally held. It seems to be imagnied that self-induction is harmful to long-distance telephony. The precise contrary is the case. It is the very life and soul of it, as is proved both by practical experience in America and on the Cont ...
